Try as I might I cannot get my iPhone 6S Plus to sync my calendars on Outlook.

[iMore Question]

I have three email accounts, my office, home and personal but the only calendar that will sync is my office one and I need to change to my personal one. I've read through various tips but nothing seems to fix this.

Do you have the Outlook email on the phone? If so, try going to Settings > Mail, Contacts and Calendar > Outlook mail> Toggle Calendar on. If it's already on, toggle it off, then back on.

I don't have any problems syncing with Outlook.com on my iPhone 6 Plus and iPhone 6S Plus. Delete the account from your device and then re-configure it on the device.
